Tech Xplore / Scientists develop near-invisible solar cells that could turn windows into power generators
Imagine a car whose windows and sunroof can help top up its battery while parked under the sun, or a pair of smart glasses whose lenses can harvest light to power built-in electronics.
Phys.org / Asteroid 2022 OB5 spins too fast for current prospectors, highlighting the divide between 'accessible' and 'exploitable'
Asteroid mining seems simple in theory. A spacecraft flies up to a giant rock in space, scoops out some material, and either processes it on site or returns it back to a huge central processing facility. But in practice, ...
Phys.org / Coal pollution is cutting solar power output worldwide, study finds
New research led by the University of Oxford and University College London (UCL) has revealed that pollution from coal-fired power plants is significantly reducing the energy output of solar photovoltaic (solar PV) installations, ...
Phys.org / Rare seals hide in underwater bubble caves to escape tourists
The uninhabited islet of Formicula in Greece's Inner Ionian archipelago is a popular tourist draw for its clear waters, swimming spots, and marine diversity. A major attraction is the Mediterranean monk seal, one of the world's ...
Phys.org / How a 4,000-year-old city defied history's 'rules' by becoming more equal as it became more successful
For decades, historians have generally agreed that the progress of small villages as they evolved into cities came at the price of widening inequality. A small group of leaders, kings and priests, would inevitably seize control ...
Phys.org / Less low cloud cover lets in more heat from the sun—and may lock in centuries of sea level rise
According to NOAA, the global average sea level has risen 8–9 inches (21–24 centimeters) since 1880. The rate at which the sea level is rising is increasing, threatening coastal cities and ecosystems around the world.
Phys.org / Consistency check casts doubt on evolving dark energy
Cosmologists have long struggled to determine whether the universe's accelerating expansion is being driven by a simple cosmological constant, or whether dark energy's influence is evolving over time. In a new analysis published ...
Phys.org / If AI can translate instantly, why learn another language?
From live speech translation in video calls to auto-dubbing on TikTok, the technology to dissolve language barriers has arrived. Real-time translation powered by artificial intelligence (AI) is now embedded in everyday life.
Phys.org / Debunking a core chemistry concept taught in classrooms everywhere
A new study has revealed that a core idea taught in chemistry classrooms around the world may be wrong. Dr. Edwin Johnson, Lecturer at the University of Newcastle, co-authored the paper published in the Journal of Chemical ...
Medical Xpress / For real heart protection, the weekly exercise number climbs far beyond current advice
Adults should aim to do between 560 and 610 minutes a week of moderate to vigorous physical activity to achieve a substantial reduction in the risk of heart attacks and stroke, suggest the findings of an observational study ...
Medical Xpress / Early warning signs: Poor grip strength linked to greater odds of developing depression
Handgrip strength is the maximum force a person can apply with their hand, and it is often used as a proxy for overall muscular strength, functional capacity, and aging. Scientists have found that it can also be an indicator ...
Science X / Seen from Mars, an interstellar visitor looks completely different and changes what astronomers thought they knew
Last fall, a Chinese spacecraft orbiting Mars captured images of a comet from another star system, offering scientists a fresh vantage on a rare visitor.
